Title: Semiconductor device and high voltage circuit using the same
Inventor: KURIYAMA TOSHIHIDE
IPC: H01L29/786
Filed: 1981-10-12
Abstract: PURPOSE:To allow a gate breakdown to occur by extending a high impurity density region from an offset gate region on an insulating substrate in a projection shape and forming an intermediate terminal of the high impurity density region, thereby enabling to produce an output voltage lower than the gate withstand voltage of an IG FET of the next state while maintaining high drain withstand voltage. CONSTITUTION:An offset gate structure IG FET on an insulating substrate is obtained at an intermediate terminal electrode 11 lower than a drain voltage while maintaining substantially the same withstand voltage than the IG FET of the conventional structure. A high impurity density n type region 10 for the terminal is disposed in the vicinity of a gate electrode 6, thereby enabling to select the voltage of the terminal to less than the withstand voltage of a gate oxidized film. In case that the length of the offset gate region is 50mum and the distance between the electrode 6 and the region 10 is 8mum, even if the drain voltage is raised to 100V, the voltage of the terminal electrode can be suppressed to a value lower than 30V.

Abstract: PURPOSE: To provide a fuzzy control process which is not affected by external noise by making a result obtained by a weighting function calculation and the application of a fuzzy rule to be non-fuzzy and obtaining the true value of a suitable duty cycle. CONSTITUTION: In a control system, this fuzzy controller 101 is connected to a switching power source 102, and an input voltage Vi , a current IL on an inductor and an error E generated by an adder node 103 are received at input. An error is obtained by subtracting an output voltage Vo from a reference voltage Vref , and the input voltage Vi and the current IL on the inductor are measured by an appropriate measurement means. Also, the temperature T of a power transistor SW is also sent to the fuzzy controller 101 and measured by a temperature measurement means. As a result, direct control is performed on the switch on and off and temperature itself of the power transistor SW, the parameters are optimized, and superior performance unaffected by external noises is obtained.

IPC: B42F3/00
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To stick a patch around the punching hole in the same manner as in use of a stapler. SOLUTION: The patch sticking unit is employed for sticking a patch 64 around the punching hole made on the document P, and the patch sticking unit 10 includes a lower main body 11 for supporting the pedestal 14 rotatably and an upper main body 12 hinge-connected to one end side of the lower main body 11.

Title: Dry cell back-up circuit
Inventor: ITOYAMA MASAMI
IPC: H02M3/00
Filed: 1991-07-03
Abstract: PURPOSE:To obtain a dry cell driving circuit which can utilize the dry cell effectively by providing a sub cell power supply at the same time an additional portion for supplying power from a sub cell power supply at a consumption portion when driving a large current consumption portion. CONSTITUTION:When a logic portion 2 is operated, a DC/DC converter 1b converts a current value of a dry cell to a small current value and supplies it to the logic portion 2 since current consumption of the logic portion 2 is small. On the other hand, when an I/O portion 3 is driven, a large amount of current is consumed. Therefore. a switch portion 16 is connected and the DC/DC converter 1b converts a current which is obtained by adding a sub cell power supply 5 to a dry cell 1a to a large amount of current which is required by the I/O portion 3 and then feeds it to the I/O portion 3. In this way, by supplying power from the sub cell, only a small amount of current is consumed from the dry cell, thus enabling nearly 100% of the cell capacity to be detected and the cell to be used efficiently.

Filed: 1987-06-30
Abstract: PURPOSE:To obtain the final recognition result of the address words of respective hierarchies even if the addresses in which the address word of the highest hierarchy is omitted are filled by shifting respective comparing objects by one hierarchy as a whole and calculating similarity at every time if respective address words information and the recognition result of the address words of respective hierarchies are noncoincident. CONSTITUTION:If respective address words information and the recognition result of the address words of respective hierarchies are noncoincident, respective comparing objects are shifted by one hierarchy as a hole and the similarity is calculated at every time. Namely, if respective address words are judged to be noncoincident, sequential comparison is executed at every hierarchy with address words information below second hierarchies as the object. The final recognition result is obtained from the combination of respective address words information when similarity becomes maximum and the recognition result of the address words of respective hierarchies. Even if the addresses in which the address word of the highest hierarchy is omitted are filled in a business form, the final recognition result of the address words of respective hierarchies in the address can be obtained.

IPC: G11C11/34
Filed: 1986-07-11
Abstract: PURPOSE:To obtain a circuit where no steady current flows in a read time by providing a latch circuit between a reading circuit and a transfer gate. CONSTITUTION:When a memory cell 8 is selected by word lines 3 and 4, the output of an inverter 14-2 of a latch circuit 14 rises up over the threshold voltage level of an inverter 14-1. Then the output of the inverter 14-2 rises more up to a power supply voltage level. Thus the input of a reading circuit containing NOR gates 15 and 17 is never floating. In addition, power consumption is also reduced for latch circuits 14 and 16.
